Spool brake device for dual-bearing reel

Abstract

The present spool brake device is configured to brake a spool, rotatably mounted to a reel unit, by a centrifugal force. The present spool brake device includes a rotary member, a brake drum and a brake shoe. The rotary member is configured to be rotated in conjunction with a rotation of the spool. The brake drum is disposed in an alignment with the spool along a rotational axis of the spool and is mounted to the reel unit. The brake shoe is contactable to an outer periphery of the brake drum and is pivotably supported by the rotary member, with a center of gravity of the brake shoe being located radially outside the brake drum.

 the brake shoe includes a contact part configured to be contacted to the taper part, and 
 the contact part is configured to be contacted to the taper part from a side of the taper part having a smaller diameter than a diameter of an opposing side of the taper part. 
 
     
     
       4. The spool brake device according to  claim 1 , wherein a radial distance between the rotational axis of the spool and the center of gravity of the brake shoe is longer than a radial distance between the rotational axis of the spool and the pivot center of the brake shoe. 
     
     
       5. The spool brake device according to  claim 1 , wherein the rotary member includes a holder by which the brake shoe is non-pivotably held. 
     
     
       6. The spool brake device according to  claim 5 , wherein
 the brake shoe includes a center-of-gravity part in which the center of gravity is located, and 
 the holder further restricts the center-of-gravity part from being contacted to the brake drum. 
 
     
     
       7. The spool brake device according to  claim 1 , wherein the rotary member includes a pivot shaft, by which the brake shoe is pivotably supported, and a hole, to which the pivot shaft is fitted. 
     
     
       8. A method of manufacturing a spool brake device for a dual-bearing reel, the spool brake device to brake a spool, rotatably mounted to a reel unit, by a centrifugal force, the method comprising:
 disposing a brake drum in an alignment with the spool along a rotational axis of the spool, the brake drum mounted to the reel unit; and 
 pivotably supporting a brake shoe by a rotary member to be rotated in conjunction with a rotation of the spool, the brake shoe contactable to an outer periphery of the brake drum, with a center of gravity of the brake shoe located radially outside the outer periphery of the brake drum, wherein the brake shoe is restricted in pivoting such that the center of gravity of the brake shoe pivots in a range more separating from the spool than a pivot center of the brake shoe separates from the spool. 
 
     
     
       9. The method according to  claim 8 , wherein the pivot center is located radially outside the brake drum. 
     
     
       10. The method according to  claim 8 , wherein
 the brake drum includes a taper part having a taper shape, 
 the brake shoe includes a contact part to be contacted to the taper part, and 
 the contact part contacts the taper part from a side of the taper part having a smaller diameter than a diameter of an opposing side of the taper part. 
 
     
     
       11. The method according to  claim 8 , wherein a radial distance between the rotational axis of the spool and the center of gravity of the brake shoe is longer than a radial distance between the rotational axis of the spool and the pivot center of the brake shoe. 
     
     
       12. The method according to  claim 8 , wherein the rotary member includes a holder by which the brake shoe is non-pivotably held. 
     
     
       13. The method according to  claim 12 , wherein
 the brake shoe includes a center-of-gravity part in which the center of gravity is located, and 
 the holder further restricts the center-of-gravity part from contacting the brake drum. 
 
     
     
       14. The method according to  claim 8 , wherein the rotary member includes a pivot shaft, by which the brake shoe is pivotably supported, and a hole, to which the pivot shaft is fitted.
